The Knicks trained him as a shooter, but when Melo was out he proved he had a much more versatile game.

It was his first year in the league playing as a backup to Carmelo. He stole Novak's (arguably the best shooter in the NBA) playing time as a rookie and found away to get playing time on a team where he was never supposed to get playing time. If he was 'just a shooter' or a 'chucker', Steve Novak would have been on the court and Copeland would have been on the bench.

As a rookie who had success despite not having a consistently defined role, there is definitely the possibility he can get better. I think it's likely.

This would fit with Nurse's offensive 4-out style, which I imagine he'll be specializing in with the Raps (along with player development). Stretch 4's and big threes. You need guys who can shoot in that type of offense, so I expect to see big changes even if we decide not to go the tank route.

No confirmation, but there's been talk of Nurse joining the team for about a month now. Similarly with Tyronn Lue, but there was always the caveat that he was also being courted by Rivers for wherever he ended up. Lue got hired on in LA once Rivers went there I think, but the Nurse hiring should still be likely.
